Sanford, in the county of Grange and State of Florida, have invented anew and useful Tire, of which the following is a specification.

This invention relates to tires.

The objects of the invention are to improve the construction andincrease the durability and strength of such devices.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the coinbination andarrangement of parts and in the details of construction hereinafterdescribed 'and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of the claim without departing from the spirit of the invention.

In the accompanying drawings forming a part of thisspecificationz-Figure l is a transverse section through a wheel rim andtire arranged in accordance with the present invention. Fig. 2 isa sideelevation of the construction shown in Fig. l, partly broken away inlongitudinal section.

Like numerals indicate corresponding parts in both figures of thedrawings.

Numeral l indicates spokes in an ordinary wheel and vnumeral 2 the fellythereof. Mounted upon the felly 2 is a clencher rim 3 having inwardlycurled flanges il.

The tire of the present invention comprises an outer casing which ismade in two separate and similar sections 5 and 6, each of the sectionsbeing a counterpartof the other, the line of division of the twosections being along the center of thetread portion of the tire as wellas along the center of the inner portion of the tire. The sections 5 and6, at their inner portion, are held on. the rim 2 by means of bolts 7having enlarged heads 8 and nuts 9, the bolts7 serv'- ing not only tohold'the clencher sections 5 and 6 in the clencher rim 3, but also tohold said clencher rim upon the wheel. The outer or tread portions ofthe sections 5 and 6, are held together by an outer clencher rim 10,formed with inwardly curled flanges 1l embracing the annular ribs l2which are formed upon the outer portions of the sections 5 and 6 of thetire casing.

The outer clencher riin l0, upon its tread portion, is roughened in anysuitable inanner to prevent skidding or sliding. ln the embodiment ofthe invention disclosed, this roughening is produced by transversestrips 14 of leather, rubber or other suitable material, said strips lebeing secured upon the clencher rim l0 by means of rivets or screws l5.Located within the sections 5 and 6 of the outer casing is an inner tube2() which isadapted to be inflated in the well known manner. The outeror tread portion of the inner tube is covered` with a steel band or arch21. Extending outwardly from the band or arch 9.1 are curved steelsprings 22, the curve of which conforms to the curvature of the innerportions of the sections 5 and 6, the springs 22 thus converging towardeach other at their outer ends as shown. rl`he band or arch 21 serves toprevent damage to the inner tube 2O but in event that said tube shouldbecome deflated for any reason, the springs 22 will expand against theinner'sides of the sections 5 and 6 and will thus hold them in suchseparate relation as will insure a continuance of the grip of theclencher riln 10 thereon.

The tire of the present invention is strong, simple, durable andinexpensive in construction and thoroughly eiiicient in operation.

What is claimed as new is:

A tire comprising a wheel rim, an inner olcncher rim secured thereon, anouter casing formed in two sections, the inner portion of each beingfitted into said clencher rim, an outer clencher rim for holdingtogether the outer portions of the two sections of the outer casing,said outer portions being spaced from each other, an inner tube, a steelarch surrounding the outer portion of the inner tube and conforming inshape thereto, and outwardly extending, convergent, curved springsconnected with the edges of said arch and pressed against the innersides of the Sections of said outer Casing to In Atestimonythat I claimthe foregoing hold them expanded, said springs and said as my own, Ihave hereto aixed my signaarch being crescent shape 1n cross section,ture 1n the presence of two witnesses.

and the outer endsof said springs being EMMETT H. HERNDON.
